Dewarps book page in images. Demo website: https://alan20210202.github.io/dewarp/
It is a personal hobby project, more information can be found in my blog posts:

- Safe: This is a pure web application, running directly in the browser with no backend and it never uploads the original image to any servers.
- Fast: Optimized with WebAssembly technology, the app runs fast even on mobile platforms.
- An assumption is made in the algorithm that the two vertical edges of the page in an image must be parallel. This should cover most use cases.
- It still requires users to manually outline page boundaries, which impairs user exprience and can be possibly automated with CV.
- It doesn't automatically rotate the image to the correct orientation. One may find an image in different orientation in the app from that in one's gallery app.
- On the technical side, I am new to JavaScript and Web development and I wrote all code in a single Vue Component file. Though I try to keep the code tidy there might be readability issues, and some code I wrote may not conform to best practices.
npm install
The compilation of WebAssembly code hasn't been added to the build script yet.
You may need to change Emscripten path in src/wasm/compile.bat and run it manually.
npm run serve
npm run build
npm run lint
